Raspberry Pi camera pinout outlines the signal and power layout used when attaching camera modules to Raspberry Pi boards. Knowing the correct pin positions on the CSI connector helps prevent incorrect connections and ensures your camera operates without issues.
Introduction
Raspberry Pi camera pinout boards are often used in projects involving image capture and video recording. A popular method of attaching cameras to the board is through the CSI (Camera Serial Interface). To avoid errors during setup, it’s important to review the camera pin layout.
CSI Interface Overview
The CSI interface is a ribbon connector designed for connecting camera modules directly to the Raspberry Pi. Older models like the Raspberry Pi 4 and Zero use a 15-pin connector, while the newer Raspberry Pi 5 features a 22-pin connector for more advanced camera communication.
Pin Format Differences
The 15-pin version is common across several Raspberry Pi models and supports standard camera modules. The 22-pin layout offers more data lanes, allowing better support for high-resolution and dual-camera configurations on models like the Raspberry Pi 5.
Typical 15-Pin CSI Connector Layout:
Ground
CAM_D0_N
CAM_D0_P
Ground
CAM_D1_N
CAM_D1_P
Ground
CAM_CLK_N
CAM_CLK_P

CAM_IO2
CAM_IO3
3.3V Power
Importance of Reviewing Pinout
Being familiar with the pinout helps prevent incorrect wiring. Connecting the ribbon cable the wrong way or supplying voltage to the wrong pin can result in hardware failure or a non-functional camera.
Using Adapters and Custom Boards
Some users prefer using adapter boards to connect different camera modules or support dual-camera configurations. These boards convert one pin format to another, but it’s still essential to reference the original pinout when connecting them to avoid miswiring.
Conclusion
Taking time to review the Raspberry Pi camera pinout before setup can prevent common connection mistakes. Whether you're working on a home automation project or a custom imaging solution, getting the camera connection right is an important first step.
